The Magicshine PMJ-875 Diving Flashlight with a high brightness Luminus SST-50 LED produces 1200 lumens of bright white light in a full sized, waterproof package. The diving light body is precision machined from Aircraft Grade 6061-T6 aluminum alloy with a hard anodized finish. Double O Rings on the tail cap closure form a watertight seal good to 100 meters in depth. The PMJ-876 has four modes of operation: High, Medium and Low, and SOS, operated by a magnet ring dimming switch. The unique magnet switch glows Green, Blue and Red, indicating the remaining time on the battery. It can be rotated easily by thumb and forefinger while holding the light in one hand. A rubber protected tether includes a jam cleat for securing the light to your wrist. The PMJ-876 is powered by six 18650 rechargeable lithium ion batteries sealed in the body of the light. A plastic plug protected port under the tail cap is used to recharge the batteries. The light has a continuous run time of up to 2.7 hours @ 100%. The batteries can be fully recharged in about 3 hours using either the AC or DC charger adapters included with the light. Extra O Rings and flashlight bag are also included.
